GPUhack dev ops

Recipe for setting up dev env at login2:

git clone https://github.com/McStasMcXtrace/McCode.git
ln -s ~pkwi/pgi/ pgi
ln -s ~pkwi/nsight-systems/ nsight-systems
mkdir McStas
mkdir McStas/mcstas
ln -s ~pkwi/McStas/mcstas/miniconda3/ McStas/mcstas/miniconda3 

Next, add these lines to your .bashrc

export PATH=$HOME/McStas/mcstas/miniconda3/bin:$PATH
module load mpi/3.0.0-gcc-6.4.0
export PATH=$HOME/pgi/linux86-64/19.4/bin/:$PATH
export PATH=$HOME/nsight-systems/bin:$PATH

(log out and log back in or source .bashrc for the remaining setup.)
